IMPROVEMENT IN CATCH-HOOKS FOR SUSPENDING LEATHER.

Specification forming part of Letters Patent No. 187,456, dated February 20, 1877; application filed January 12, 1877.

To all whom it may concern Be it known that we, CYRUS CHAMBERS, Jr., and J CHN T. CHAMBERS, jointly with the late EDWIN CHAMBERS, deceased, of Philadelphia, Pennsylvania, invented certain new and useful Improvements in Catch-Hooks for VHanging Leather, 85C.; and we do hereby deelare the following to be a full and correct description of the same, reference being had to the accompanying drawings, in which- Figure 1 is a side elevation of our improved hook attached to a beam. Fig. 2 is an edge view of the same.

The same part is marked by the same let ter in both figures.

Our invention consists of various improvements in the construction of the catch-hooks in common use, by which they are much better adapted to perform the work for which they are intended. These improvements consists in restricting the motion of the hook to alimited back and forth movement, making each hook a right and left, capable of being applied to either side of the supporting-beam, while the points of the hook are all in one div rection, making the jaws of a sufficient length to take in a Considerable portion of the suspended material to prevent its breaking when damp and tender; making the bearing ofthe latch and jaw wide and large, to give ample holding surface leaving a small space between the end of the latch and jaw to prevent rusting and clogging; providing the latch with stops` to limit its motion in both directions, keeping it from falling below the horizontal position, and throwing it down before it reaches a vertical one; and, finally, giving a flaring mouth to the stationary jaw, to facilitate the introduction of the material to be suspended.

Our improved hook is clearly represented in Fig. 1 of the drawing. It consists of a head, B, having two long jaws, J J', with an opening between them, one ofsaid jaws, J', having at its end a large curved pointed palm, D, and the other, J, provided with a latch or pawl, C, pivoted at a to the jaw J, and having an up-and-down vibrating movement. The latch Gis provided with a stop,

8, which prevents it from falling below a horizontal position, and the shape oi' the latch is such that it strikes the inner edge of jaw J before it reaches a vertical position, and is thrown down toward the horizontal again. The shoulders ot the hook are provided with lugs or teats t t, and the head is pi'voted to either side of a supportingbeam, A, by a pin, p, on which the hook is so suspended that it can swing back and i'orthin one plane-a distance limited by the striking of the lugs t t against the under side of the beam A. The lugs project from both sides of the jaws, as

seen in Fig. 2, in order that the hooks may be hung on both sides of the beam Aand still keep the points of the palms D all in the same direction.

lt is desirable to hang the hooks on both sides of the beam, in order to prevent canting and warping; and it is desirable to have the hooks all pointing one way to facilitate the insertion and release of the material..

The operation is as follows: To insert the material, push upthe latch C, with the edge of the leather or pasteboard, and raise it -until a sufficient holding-surface has been introduced; then press the material against the jaw J' when the latch C will fall and clamp it. To release the dried material, raise it up and press it toward the latch, when the latter will stand nearly perpendicular, and allow the leather or board to be withdrawn. The latch then falls to its original position.
